Crops were grown at the experimental farms using accepted cultural practices (within the limits of experimentation) or trials were conducted on growers' fields. Most experiments were designed as randomized complete blocks with three to five replications. Herbicide treatments were applied uniformly with precision plot sprays. Unless otherwise indicated, preplant herbicide...
The objectives of this project were to evaluate the efficacy of common row crop herbicides for control of puncturevine, and determine the effect of post harvest weed management strategies on hairy nightshade seed development.
Weed management is a continual challenge to Oregon table beet growers. Research over the last several years has documented that s-metolachlor (Dual Magnum) will substantially improve weed control and crop yields when applied alone or in concert with other registered herbicides such as Roneet and Pyramin, with the potential to...
Summary
Irrigation effects on root rot and yield
Reducing irrigation during the first 6 weeks after planting reduced root rot of sweet corn at midseason and at harvest, consistent with findings of the past two years.
Reducing the early season irrigation level increased yield of Jubilee by 20%...
Cancellation of the registration of an effective bean mold fungicide, Ronilan, is slated to occur at the end of growing season in 2005. Finding equivalent alternatives by 2006 for use in snap bean is critical. The goal of the project is to continue evaluations of alternative fungicides for their effectiveness...
The objective of the study was to compare crop tolerance of carrots and parsnips to two soil and early postemergent herbicides. Dual Magnum (s-metolachlor) was recently registered for use on root crops, but provides poor control of hairy nightshade, and looses effectiveness if rainfall is excessive after application.
Cancellation of the registration of an effective bean mold fungicide, Ronilan, occurred at the end of the 2005 growing season. Finding equivalent alternatives for use in snap bean is critical. The goal of the project is to continue evaluations of alternative fungicides for their effectiveness in controlling white mold (Sclerotinia...
SUMMARY
• Impact and Laudis herbicides were evaluated for wild proso millet and broadleaf weed
control in sweet corn.
• The most effective treatments were Impact and Laudis applied with Outlook and atrazine at
V2-3.
• Increasing the methylated seed oil (MSO) rate from 0.25% to 1 % was more...
